IPC: G11B5/187
Filed: 2002-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a magnetic head with which a worn amount can be visibly and clearly detected without punching a mark.  <P>SOLUTION: The device is a magnetic head 1 with a groove 12 formed in the sliding direction on the sliding surface on which a magnetic recording medium slides, and the groove 12 is formed so that the width becomes narrower toward the bottom 12c.

IPC: C02F1/28
Filed: 2002-11-25
Abstract: <P>PROBLEM TO BE SOLVED: To develop a water cleaning method which can flocculate and sediment a fine suspended component and can also remove metal ions caused by a metallic flocculant at the same time.  <P>SOLUTION: In this water cleaning method, a radiation crosslinking material of a polyamino acid or its salt is charged in water to be treated when the concentration of the metallic flocculant added to the water is M (mg/l) and the concentration (m) of the radiation crosslinking material is regulated to 0<m≤M/2 (mg/l) to reduce the concentration of residual metal ions in the water. The radiation crosslinking material and the metallic flocculant can flocculate and sediment a suspended substance (COD component, a BOD component, an SS component or the like) in the water with high efficiency. Since the radiation crosslinking material has a property for trapping metal ions remaining in the water, residual metal ions are reduced suddenly. Further, polyamino acids have high safety because of food and a cleaning cost is reduced because the addition amount of the radiation crosslinking substance is 1/2 or less of the amount of the metallic flocculant.  <P>COPYRIGHT: (C)2004,JPO
